Fault Codes and Volt-Ohm Meter (VOM)

Diagnostics

ZF FreedomLine

transmission control unit (TCU) uses a

series of fault codes to identify system malfunctions that

the TCU detects and stores into memory.

After you retrieve a fault code from the instrument panel

display and identify the fault, use a volt-ohm meter

(VOM) to test the area where the fault code indicates

that the malfunction has occurred. An authorized

distributor/dealer should repair the fault.

How to Retrieve Active and Inactive

Fault Codes from the Instrument Panel

Display

NOTE: The vehicle must be stationary to retrieve active

fault codes.

1. Park the vehicle and set the parking brake. Turn the

engine OFF, but leave the ignition ON. Prepare to

record the fault codes before you begin to retrieve

them from the instrument panel display.

2. Use the following procedures to retrieve active and

inactive fault codes.

Active Fault Codes

NOTE: All active fault codes will steadily display for

approximately 1-1/2 seconds each. Ignore fault codes

that flash. When the TCU has listed all active fault

codes, the list will repeat.

1. Press and hold the NEUTRAL button and FUNCTION

button at the same time. The TCU will begin to list

the active fault codes on the instrument panel

display.

2. Record the fault codes.

3. When you’re finished retrieving fault codes, release

the NEUTRAL and FUNCTION buttons. Turn the

ignition OFF.

Inactive Fault Codes

NOTE: All inactive fault codes will steadily display for

approximately 1-1/2 seconds each. Ignore fault codes

that flash. When the TCU has listed all inactive fault

codes, the list will repeat.

1. Press and hold the NEUTRAL button, FUNCTION

button and service brake at the same time. The TCU

will begin to list the inactive fault codes on the

instrument panel display.

2. Record the fault codes.

3. When you’re finished retrieving fault codes, release

the NEUTRAL and FUNCTION buttons, and the

service brake. Turn the ignition OFF.

To View Active or Inactive Fault Codes

Again

Repeat the previous steps.

How to Clear Inactive Fault Codes from

TCU Memory

NOTE: Inactive faults are repaired active faults that

have not been cleared from TCU memory.

1. The vehicle must be stationary to clear inactive fault

codes. Park the vehicle and set the parking brake.

Turn the engine OFF. Turn the ignition OFF.

2. Press and hold the NEUTRAL button and the

FUNCTION button at the same time.

3. Turn the ignition ON. Do not start the engine. Count

to three and release both buttons.

4. Count to three and press and hold the NEUTRAL

button and the FUNCTION button at the same time.

5. Turn the ignition OFF. Count to three and release

both buttons. The fault codes will be cleared from

TCU memory.
